This doorway is an excellent example of medieval reuse of materials. The principal elements were carved at different times, displaying divergent styles and techniques, and were combined in a medieval remodeling. The lions, too, were taken from an earlier monument. All of the marble used to make the portal originally came from the ruins of Roman buildings in the vicinity. The decorative forms show the survival of both classical and Langobardic elements in Romanesque sculpture.
